Writing React Forms Like a Pro with Formik

## What is Yup?
Writing a form's validation logic manually is usually not the most interesting task, especially when the form has a lot of constraints to test against. There are many JavaScript libraries that help simplify the validation process for the developer. Yup is one such library.

Yup makes it extremely easy for us to write the validation logic of our form with more concise, easy-to-understand lines of code. And because a lot of people use Yup together with Formik, the Formik team introduced a prop called `validationSchema` in the `formik` object. This prop receives a Yup validation schema object as its value.
